Abstract
A novel method synthesized of silicon carbide nanowires (SiC NWs) by current heating of a silica-alumina-graphite rod was investigated. We utilized an iron impurity in the raw materials as a catalyst for the VLS process. The rod was placed between two copper electrodes and gradually heated up to about 1400 o C by passing current though it under flowing argon. Hundreds of the milligrams of as-synthesized NWs, formed on the surface were then characterized using scanning electron microscopy, transmission electron microscopy, energy dispersive analysis of X-ray, selected area electron diffraction, X-ray diffraction and Raman spectroscopy. An increasing of a non-uniform shell thickness was observed when added alumina at higher weight ratio.
